We have a 3 server BES 4.1.2 environment. One user on the 02 server was experiencing alot of pending messages. No other users on the 02 server or the backend server were having the same problem. We had the user delete the desktop CMIME and resent a new one. The user received the new service book and was still experiencing occasional pending messages (once or twice an hour). We moved the user to the 03 server and delivery returned to normal.

It was my interpretation that pending messages would be a device, carrier or coverage problem. Can anyone think of something else? Why would moving the user fix the problem?
